Leveraging Interactive Geometry Software to Prompt Discussion

  • Leveraging Interactive Geometry Software to Prompt Discussion

    Assess the robustness of students’ understanding of polygons and move students beyond drawing to constructing geometric shapes.
    Ask your students to construct a square. What do you think they might do? Some students may use a ruler to create a square-like figure, which they may justify as being a square by stating that the figure has four congruent sides but neglecting to confirm the angle measures. What if you asked them to create a square using interactive geometry software? Although the software can encourage a greater level of precision than pencil-and-paper representations, students may still produce a shape much like that shown in figure 1.
